  • Speed=30km/h
  • Time=21/2=10.5h


\\ \tt\hookrightarrow Speed=Distance/Time


\\ \tt\hookrightarrow Distance=Speed* Time


\\ \tt\hookrightarrow Distance=30(10.5)


\\ \tt\hookrightarrow Distance=315km

Answer:

  • 315 kilometers.

Explanation:

We know that:

  • 30 kilometers = 1 hour

Solution:

  • 30 kilometers = 1 hour
  • => 30 x 21/2 kilometers = 21/2 hours
  • => 15 x 21 kilometers = 21/2 hours
  • => 315 kilometers = 21/2 hours

Hence, in 21/2 hours, the cyclist rides 315 kilometers.
